Grapevine plant named ‘Sheegene 25’

- Sheehan Genetics, LLC

A new and distinct grapevine plant named ‘Sheegene 25’, characterized by the following unique combination of characteristics: ‘Sheegene 25’ a cultivar developed as a table grape having berries that are large, red, and seedless. The large berries are approximately 7 g each naturally and without girdling or application of plant growth regulators. Harvest is during August when maturity reaches 17-22° brix.

Latin name of the genus and species of the plant claimed: Vitis vinifera.

Variety denomination: ‘Sheegene 25’.


The present invention relates to a new and distinct variety of grapevine named ‘Sheegene 25’. ‘Sheegene 25’ produces large, red, seedless grapes on bunches for use as a table grape. The variety originated from a cross of ‘Princess’ (unpatented) as the pollen parent and ‘Red Globe’ (U.S. Plant Pat. No. 4,787) as the seed parent. ‘Sheegene 25’ was asexually propagated in the dormant season of 2004 by grafting on Thompson 2A, virus free rootstock, in a Vitis vinifera variety block located near McFarland, Calif. All characteristics and distinctions remain true to form and are established and transmitted through succeeding propagations.


The present invention relates to a new and distinct grapevine plant, which will hereinafter be denominated as ‘Sheegene 25’. ‘Sheegene 25’ produces large berries averaging 7 g per berry without girdling or application of plant growth regulators. The berries are harvested in August when maturity reaches 17-22° brix. Comparison can be made to ‘Scarlet Royal’ (U.S. Plant Pat. No. 16,229), ‘Crimson Seedless’ (unpatented), and ‘Ruby Seedless’ (unpatented), all of which are also red, seedless cultivars that harvest during the same period in August in the San Joaquin Valley. ‘Sheegene 25’ is distinct from these cultivars in a number of ways, the most obvious of which are as follows:

    • Berry Size: ‘Sheegene 25’ berries are very large, weighing 7 g. ‘Crimson Seedless’, ‘Scarlet Royal’, and ‘Ruby Seedless’ berries are smaller, weighing 4.5 g, 5.8 g, and 3.0 g, respectively.
    • Berry Shape: ‘Sheegene 25’ berries are uniquely truncate in shape, whereas ‘Crimson Seedless’ and ‘Scarlet Royal’ are ovoid, and ‘Ruby Seedless’ is round.
    • Cluster Density: ‘Sheegene 25’ clusters are medium to loose, whereas ‘Scarlet Royal’ and ‘Ruby Seedless’ are tight and usually require berry thinning to loosen the cluster. ‘Crimson Seedless’ clusters are of medium density with berry thinning required in some years.
    • Leaves: The leaves of ‘Sheegene 25’ are pentagonal with deeply lobed lateral sinuses. ‘Scarlet Royal’ and ‘Ruby Seedless’ and, to a lesser degree, ‘Crimson Seedless’ have lateral sinuses that are much less deeply lobed.

‘Sheegene 25’ can be distinguished from its parent cultivars based on at least the following characteristics:

    • Seeds: No seeds are present on the berries of ‘Sheegene 25’, whereas parent cultivar ‘Red Globe’ is seeded.
    • Color of Berry Skin: ‘Sheegene 25’ berries are red in color, whereas parent cultivar ‘Princess’ berries are yellow-green in color.

‘Sheegene 25’ can be distinguished from its sibling cultivars based on at least the following characteristics:

    • Tendril Form: ‘Sheegene 25’ tendrils are 50% bifid and 50% trifid, whereas sibling cultivars ‘Sheegene-3’, -9’, -12’, -13’, -17’, -18’, and -21’ tendrils are entirely bifid, sibling cultivar ‘Sheegene-1’ tendrils are bifid and occasionally trifid, sibling cultivar ‘Sheegene-22’ tendrils are trifid and occasionally trifid, and sibling cultivar ‘Sheegene-24’ tendrils are 50% trifid and 50% quadrifid.
    • Berry Shape: ‘Sheegene 25’ berries are truncate, whereas sibling cultivars ‘Sheegene-1’, -3’, -9’, -12’, -13’, -17’, -18’, and -21’ berries are ovate, and sibling cultivars ‘Sheegene-22 and -24’ berries are broad ellipsoid.


‘Sheegene 25’ is illustrated by the accompanying photograph, taken of a 5-year-old vine, which shows the plant's vines, foliage, and fruit. The colors shown are as true as can be reasonably obtained by conventional photographic procedures.

The FIGURE shows the typical vegetative morphology of stems, leaves, and tendrils.
